I think it's always good to tell what you know. It's even worse to conceal the things you know.
It's not all about knowing and being 100% correct here all the time. Some things turn educative within an open discussion about a topic and I like this.
I'm not here to be correct with every breath I take and I don't care if I'm wrong sometimes. I am open for any kind of answers, as long as they are constructive.
It doesn't always help that much more, to give stereotype answers.
